Constituent dispersion · breadth vs the index
RUBIN — Rubin Build-Out 100 (EW)
Divergence over time — price vs breadth, by horizon
The hero read is the 1-month picture; here the same price↔breadth divergence across 1 week / 1 month / 1 quarter, computed over the 126-session history. A/D /name is net advancers-minus-decliners per covered constituent; % beating Δ and median−ETF Δ show how participation shifted. Price rising while those fall = the move is narrowing under the surface.
| Horizon | Price | A/D /name | % beating Δ | Median−ETF Δ | Read |
|---|---|---|---|---|---|
| 1 week | -6.89% | -2.05 | — | — | Confirming ↓ |
| 1 month | +8.91% | +2.56 | — | — | Confirming ↑ |
| 1 quarter | +2.49% | +0.27 | — | — | Confirming ↑ |
Over the last 126 sessions: price up +22.76%, breadth up (+0.5/name) · % beating 42→43 · median−ETF -2.69pp→-1.31pp.
Stocks above their moving average — participation breadth
Of the 129 covered constituents, the share trading above each simple moving average — the classic breadth gauge. A firm index price with a low %-above-MA is a narrow, top-heavy tape. As of 2026-10-13.
New highs & new lows — by horizon
How many of the 129 covered constituents closed today at a new high (or low) over each window, and the net. A shrinking net as the index holds up = fewer names leading.
| Horizon | New highs | New lows | Net |
|---|---|---|---|
| 5-Day | 5 (4%) | 90 (70%) | -85 |
| 1-Month | 5 (4%) | 10 (8%) | -5 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | -0.06% | -1.97% | -1.91pp | 23 / 105 | 24 / 105 | 29 of 129 | ±2.6% |

Median − ETF below zero means the typical name is lagging the cap-weighted index — the move is top-heavy. "Beat" counts constituents outperforming the ETF over the window. Dispersion is the cross-sectional standard deviation of constituent returns — high = a stock-picker's tape, low = pure beta.
What drove the move — contribution = weight × return

FAQ · from the current data
RUBIN dispersion — data Q&A
Is RUBIN's move broad or carried by a few names (21 sessions)?
As of 2026-10-13: over 21 sessions the fund returned +8.91% while its median constituent returned +2.84% — a dispersion of 9.85 pp; 24% of 129 members beat the fund. Broad advance - breadth is rising with price.
How did RUBIN's members trade in the last session?
As of 2026-10-13: fund -0.06%, median member -1.97%, 23 advancers vs 105 decliners.
What does the dispersion page for RUBIN measure?
It splits the fund into its members: the fund's own return against the median constituent, how many members beat the fund, advancers vs decliners, and a cumulative advance/decline line that tends to lead price. A firm fund price with a weak median and a falling A/D line is a narrow, top-heavy tape; a broad move shows the median keeping up. 129 constituents covered, re-baked nightly from the Closelooknet lake.
Is this investment advice?
